SCREEN-DOOR STRUCTURE.

Application filed April 25, 1923.

T 0 aZZ whom it may concern:

Be it known that CoRNnLUs VERDUIN, a citizen of the United States,residing at Croo-kston, in the county of Cherry and State of Nebraska,has invented certain new and useful Improvements in Screen-DoorStructures, of which the following is a specification.

This invention has reference to screen door structure for preventing theentrance of flies or other insects into houses during the summer timeand its object is to provide means whereby the screen is rendered moreefficient for keeping the flies out than has heretofore been the case.

Since most of the flies, which in spite of a screen door, find their wayinto a house come in through the opening at the top of the door when thedoor is swung ajar, the purpose of the device is to close that opening.

Another advantage is that the screen door cannot blow open past thecenter as is so often the case with outside screen doors.

In order to render the structure more efiicient than heretofore thecontrivance opens and folds much after the fashion of a fan.

There is provided a member or strip of wood which may be two feet, sixinches long and one-half inch in thickness and in width may taper fromone and one-fourth inches to one-half inch.

There is also provided certain rods which are stationary and fastened towooden strips. Other r ds are also stationary and fastened to the screendoor. To these rods there is fastened a web of light canvas insubstantially the shape of a segment since the circle of which thescreen door is a radius and a shape defined by other of the rods doesnot have the common center, it is necessary that the cloth be fastenedcorrespondingly so that the cloth will not pull. Extending through thecanvas parts there is provided alight chain and the arrangement is suchthat the device must be reversible so as to fit both'right and leftdoors.

Hanging down from the rods there are rectangular shaped pieces of clothwhich in conjunction with the structure give added protection againstflies trying to get under the canvas when the door is swung open.

The invention will be best understood from a consideration of thefollowing de: tailed description taken in connection with e acco p nyidrawings pa Serial No. 634,454.

of this specification with the understanding, however, that theinvention is not confined to any strict conformity with the showing inthe drawings but may be changed and modified so long as such changes.and modifications mark no material departure from the salient featuresof theinvention as expressed inthe appended claim.

In the drawings:

Figure -1 is a plan view of the screen frame structure with the doorframe in cross section and the parts extended;

Figure 2 is a section on the line 2-2 of Figure 1;

Figure 3 is a perspective view of a slidable rod entering intothestructure;

Figure 4 is an enlarged detailed view of one end of one of the stripsentering into the structure; and

Figure v5 is a view of a casing by means of which the structure isassembled.

Referring to the drawings, there is showna frame 1 composed of spaceddoor jambs with spacing members 2 made fast at the top of the door tothe said frame, the full width of the door with the spacing membersfastened to the top of the door frame by screws 3 or any other suitablemanner and including a block 4 fastened to the top of the door jamb byscrews 5 which also serve to hold a series of bars 6 hinged at one endto a block 7 made fast to the member 91 by means of pins'8 arranged in aline transverse to the bar 2 and spaced apart crosswise of the block 7.

The bars or strips 6 radiate from the pivots 8 toward the margins of acloth member 9 to which the ends of the bars or rods 6 are. secured byfasteners 10 and these bars are joined at the ends remote from thepivots 8 by chains 11 each of a length corresponding to the length. ofthe chains 11, the terminal one of the chains being secured to a hook 12at one endof the terminal bars or rods 6. The bars 6 are splayed withrespect to the block 7 so that the bars 6 move about the pivot 8 inspaced relation to each other so that the several bars 6 move aboutindividual pivots 8 in turn movable in spaced relation to each other.

The end frame 1 has connected thereto by means of a hinge 13 a door 14which may be turned in parallel relation with the member 2 or at rightangles thereto.

Since the cloth member 9 changes its relaties o the a s 6 Whe h r i i hng ar my GA relation or parallel relation to each other the clothiii-ember 9 folds uponitself in one position or the other of the bars 6and in order to compensate for this changing relation the cloth member 9adjacent to the bar 14 is provided with numerous parallel slits 15.

Each member 2 is provided Witha through slot 16 in Which is lodged a web17 Which may be made offibrous material such as cardboard or the likeand held to each member 2 by strands 18 allowing. the Web 1 7 to turnabout fasteningdevices 19 so as to fold against the member 2 as neededso as to allow the Web 17 to fold against the member 2, permitting thefabric 9 to be folded in such manner as to contract into the spaceoccupied by the member 9 and thebars 6 or to permit the fabric to bestretched.

I The purpose ofthe Webs 17 is to exclude flies or other insects fromthe spaces between the bars 6. The members 2 are secured to the block 4:by screw connections 20 to permit the bars 2 to be swung about thescrewsor pivots 20 toward and from the end member 2 or toward and fromthe eorrespodingv end bar or end member 14: as

occasion demands, the fly shields 21; made fast to the members 2 by thefastening devices 19.

What is claimed is: p

A screen structure adapted to be used in conjunction with a doorhingedly mounted in a frame comprising a block adapted to be applied tothe inner surface of the frame at the corner thereof, and adjacent thehinged edge of the door, bars pivotally mounted at one end upon theblock and disposed transversely of the door and the door frame, saidbars being provided with longitudinally disposed herfs leading in fromthe outer free ends thereof, a bar adapted to be applied to the deerframe, a bar adapted to be applied to the door, a flexible f abricmaterial secured at its edges t0 the bars which. are applied to theframe a "l door respectively, the int ri-n'edi ate port of the fabriebeing trained threuglr th provided in the pivoted bars and a: fl bindingelement connected with the outer edge of the fabric and secured atintervals to the said bars.

in testimony whereof I afl'ix my signature.
